2CV HEATING AND VENTILATION SYSTEM

What are the main parts of the 2CV ventilation and heating system?

It is well known that the state of conversation of the ventilation flap is one of the essential points necessary to evaluate the health of a 2CV. It is also important to check the heating tubes and heat exchangers, which heat the interior, circulate the air and cool the engine. They are therefore central elements under the bonnet of your car with two chevrons.
Other elements that deserve your attention are the ventilation flap seal, the air vent grille, the long and short cables of the heating control, which are all part of the ventilation and heating system of the famous 2CV. This system also includes exchanger sealing foams to be placed on each side of the exchanger's inner flap so that the air is completely evacuated. The accessories that will allow you to fix and supply air to your heating system and its controls are made up of fixations, cable clips, jubilee clips, as well as a series of heating tubes fixed to the heating connections on the bulkhead, the whole forming the famous "heating box".
Finally, in order to maintain control of the ventilation or temperature of the passenger compartment, the heating lever and the ventilation flap control will be used to obtain an ideal ambient air temperature. Another important part is the ventilation grille, which prevents insects or mosquitoes from visiting you during your journeys!

What are the specificities of the ventilation and heating system for 2CVs depending on the year of production?

The year of production of your car will allow you to choose between the felt heater tubes known as "old models" fitted to vehicles produced before 1970 and the cardboard tubes, with a foam interior, which are intended for the 2CV6 and 2CV4 models, marketed from 1970 on.

Short or long heating tubes?

Your 2CV will need both types of heater tubes : the short tubes to evacuate the hot air from the engine circuit directly to the outside, and the long tubes to supply the passenger compartment with the hot air from the circuit. These ducts are activated by the heating control on the dashboard, which depending on its setting, activates the flap inside the heat exchanger to supply the short or long tube with hot air!
The defrost control is also particularly useful in winter, when the lever is pushed upward it raises the flap on the heater box to release warm air towards the windscreen and allow it to defrost. For more "aesthetic" finish, you will find in our online shop a ventilation flap in stainless steel to decorate the exterior of your vehicle. We also offer you a stainless steel heating lever that is more upmarket than the standard one, as these levers are common to the various models derived from the 2CV, such as the Dyane or the Mehari.
